1. CONTRAST OF MISCELLANEOUS PARTS
NOTES : ÷ Parts marked by � NSP � are generally unavailable because they are not in our Master Spare Parts List. ÷ The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. ÷ Reference Nos. indicate the pages and Nos. in the service manual for the base model. ÷ When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J = 5%, and K = 10%). 560 � = 56 � 10 1 = 561 ................................................... RD1/4PU 5 6 1 J 47k � = 47 � 10 3 = 473 .................................................. RD1/4PU 4 7 3 J 0.5 � = R50 ...................................................................... RN2H � 5 0 K 1 � = 1R0 ......................................................................... RS1P 1 � 0 K When there are 3 effective digits (such as in high precision metal film resistors). 5.62k � = 562 � 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F
